PipeTech acquired the technology and developed the most advanced leak detection and location system in the world. The system, under the brand name WAVEGuard® LDS, consists of the following components:
The WAVEGuard® system uses intrinsically-safe high quality pressure transmitters. These pressure transmitters are responsible for pressure signal acquisition and transmission and are strategically installed at various locations along the pipeline.
The Field Signal Processor (FSP) unit/panel is field level equipment for pipeline leak detection and location system. This unit is designed and manufactured by PipeTech. It is an integrated field-grade outdoor system which includes modules for data acquisition, signal conditioning, noise filtering, digitalsignal processing and communication.
The FSP unit is an environmentally-hardened system that is designed to operate under harsh environment and extreme temperatures, and is customized for different projects and pipelines.
The FSP unit monitors the conditions in the pipeline and processes the events which are sent to LDS Master Central Controller (CC) unit3. Central Controller (CC) unit, also known as the Master LDS, which communicates with the FSPs, collects pressure events, and makes leak decisions.
The LDS Master Central Controller (CC) unit is the brain of the WAVEGuard® LDS system. The CC unit is designed and manufactured by PipeTech, and its cabinet is customized to fit the needs of the LDS project.
The CC unit communicates with all the Field Signal Processor (FSP) units on the pipeline. It is responsible for collecting pipeline events from all the FSP units in the system and for determining if a leak has occurred at any point along the pipeline. It also uses directional filtering mechanism to filter out noise coming from outside the protected pipeline segment.
The CC unit is responsible for declaring leaks and computing their locations. Redundancy with Active/Standby configuration is supported.
The CC unit is connected with the Central Monitoring Station (CMS) computer via client provided backbone communication network using TCP/IP protocol. The CC unit can be programmed for interfacing with third party systems, such as DCS and SCADA systems, using industrial open protocols, such as Modbus (Serial or TCP) and OPC.
The LDS Central Monitoring Station (CMS), also known as the LDS computer, used for supervisory and configuration operations. The CMS is typically a high-end general-purpose computer running HMI application for system operation & configuration functions.
